METHODS： One hundred and seventy-seven consecutive outpatients scheduled for colonoscopy were randomized in one of four groups to receive polyethylene glycol electrolyte solution or oral sodium phosphate with two different timing schedules. Quality of cleansing, polyp detection, and tolerance were evaluated. RESULTS： Patients receiving polyethylene glycol or sodium phosphate on the same day as the colonoscopy, obtained good to excellent global cleansing scores more frequently than patients who received polyethylene glycol or sodium phosphate on the day prior to the procedure （P 〈 0.001）. Flat lesions, but not fiat adenomas, were more frequent in patients prepared on the same day （P = 0.02）. CONCLUSION： The quality of colonic cleansing and the detection of fiat lesions are significantly improved when the preparation is taken on the day of the colonoscopy.展开更多
